Abstract: PURPOSE:To utilize ozone effectively while improving the contact efficiency of activated oxygen and a resist film, and to conduct ashing treatment rapidly by mounting a filter member attenuating wavelength light close to 253.7nm in emitted light from an ultraviolet lamp between a wafer susceptor and the ultraviolet lamp. CONSTITUTION:An ozone generator is connected to a treating chamber 10, and a wafer W, on a surface of which a resist film is formed, is placed onto a wafer susceptor 30. An ultraviolet lamp 40 radiating the resist film on the wafer W with ultraviolet rays has intense continuous spectral emission in a wavelength range of 200-300nm, and a high-pressure mercury lamp, a metal halide lamp, etc., are used. Wavelength light of 200-240nm and 270-300nm is transmitted efficiently through an ultraviolet transmitting window 50 while a filter function selectively attenuating wavelength light close to 253.7nm having a large absorption coefficient to ozone is combined. A dielectric multilayer film is evaporated and formed onto a substrate such as a quartz board in the ultraviolet transmitting window 50.

Title: Method and device for preventing thawing of snow, and compacting method and device of fallen snow in playing facilities of snow
Inventor: KISHI SUSUMU
IPC: E01H4/02
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To prevent snow from thawing and compact fallen snow, by blowing low temperature air into failed snow to penetrate it and cool the fallen snow as a whole. SOLUTION: Low temperature air is ejected from nozzles 5a of header pipes 4 laid on the whole area of a bedrock 1 into fallen snow 3 to form air holes 7 connected to the fallen snow surface in the whole snow body and evenly cool the whole snow body by forcing the low temperature air to penetrate the fallen snow 3. As the low temperature air elected from the air holes 7 to the outside of the fallen snow 3 has a larger density than the atmospheric air, it flows alone the surface of fallen snow to form a laminar flow and isolates the sensible heat transfer from the outside air at the surface of the fallen snow. The snow 3 at the periphery of the holes 7 is frozed by the low temperature air penetrating the fallen snow from the holes 7 and the hardness and the shearing strength increase.  And further, since the cold is transferred from the lower layer to the upper layer of the fallen snow in sequence, the hardness and shearing strength of the lower layer become larger than those of the upper layer. In this way, a favorable condition without peeled snow can be kept and snowslides can be prevented even if the inclined angle of the bedrock is large.

Title: Operational procedure for fluidized layer combustion device
Inventor: NOTANI TAKEO
IPC: F23C10/00
Filed: 1984-02-20
Abstract: PURPOSE:To prevent the emission of pollutional materials to increase even after a combustion device is stopped, by attempting to stop the device while controlling the supplying amount of fuel in a relative fashion to that of air and retaining an excess air ratio substantially at a constant level. CONSTITUTION:To stop boiler operation, air supplying amount is lowered to the minimum level Q1 retaining a fluidizing state for cooling down the boiler. On the other hand, the supplying quantity CQ of coal is also lowered to reflect the reducing air quantity of supply. In this case, the supplying quantity of coal is progressively reduced so that the quantity of air supplied may provide an excess air ratio of substantially 1. The control is carried out with basis on the quantity of coal prestored in a control box 13 beforehand and a theoretical air quantity needed to burn the coal quantity. In this way, it is available to provide an operational procedure for a fludized layer combustion device preventing the increase in the emission of pollutional materials such as NOX and the like even after the device stop operating.
